Cosmology: On the trail of great mysteries
The eRosita telescope's survey, led by the Max Planck Institute for Extraterrestrial Physics with significant contributions from LMU Munich, has refined our understanding of the universe, aligning with the cosmological standard model and offering insights into neutrino mass and dark energy. Prof. Dr. Daniel Gruen contributed to calibrating measurements through weak gravitational lensing, a global effort that has helped resolve the S8 tension by providing a more accurate picture of the universe's total matter and its distribution. This breakthrough, indicating a high precision match with cosmic microwave background measurements, marks a significant step in cosmology, potentially easing concerns over previous discrepancies in the field.
